Called upon by the police to investigate an unusual case of zombies kidnapping the homeless, Dr. Jack Castle is captured by the zombies and brought before their master - a 20 foot tall mad scientist known as the Zombie Master.

The evil Zombie Master turns his special ray that hypnotizes people into becoming living corpses onto the investigator. Dr. Castle resist the ray's hypnotic powers and the Zombie Master increases the device's voltage. Overloading the machine, the explosion kills the Zombie Master and the radiation grants Castle superhuman powers. With superhuman strength and able to generate intense heat, Castle dons a costume and assumes the identity of the Fiery Mask.
